I assume you're using Arnold GPU beta, because the CPU has a max texture cache size, which by default is 2GB. So on CPU you could have TBs of texture data and never use more than 2GB

For Arnold GPU, set the Max Texture Resolution in the Render Settings > System tab

If you're using CPU, then the textures are not the problem.

A max cache of 2GB means that Arnold will never load more than 2GB of texture data.

Could be displacement. Could be a number of things, I cannot tell without more information.

Can you get an Arnold log for a render? Maybe ignore textures, displacement, and subdivision, and then start turning them back on one by one.
